Mayborn v. Nutrits: Baby Bottle Patent Dispute Settled and Dismissed with Prejudice
Mayborn Group — maker of the Tommee Tippee brand — sued Israeli firm Nutrits Ltd. in Texas over US11730680B2, a patent covering silicone baby bottle design. Both sides settled within 169 days, with all claims and counterclaims dismissed with prejudice and each party bearing its own costs.
Swift settlement in the infant feeding products patent space
On 22 August 2023, Mayborn (UK) Limited, Mayborn USA, Inc., and Mayborn Group Limited — the corporate group behind the Tommee Tippee brand — filed a patent infringement action against Nutrits, Ltd. in the Eastern District of Texas (Case No. 2:23-cv-00378) before Chief Judge Rodney Gilstrap. The asserted patent, US11730680B2, covers technology relevant to the Flexy Silicone Baby Bottle and Plastic Breastmilk Baby Bottle product lines. Nutrits, an Israeli company, was accused of infringing that patent through competing products in the infant feeding accessories market.
The dispute concluded on 7 February 2024 when both parties filed a Joint Motion to Dismiss with Prejudice under Rule 41(a)(2), notifying the Court they had reached a private settlement of all claims. Judge Gilstrap granted the motion, dismissing Mayborn’s infringement claims and Nutrits’ counterclaims with prejudice. The with-prejudice designation means neither party can relitigate these same claims. Costs and fees were allocated on an own-costs basis, suggesting the settlement did not include a prevailing-party cost award.
The 169-day duration from filing to closure is notably short for patent litigation in the Eastern District of Texas, which typically sees cases run considerably longer before resolution. The rapid settlement suggests the parties may have reached a commercial arrangement — such as a licensing agreement or market allocation — relatively early in discovery, though the specific terms remain confidential. The counterclaims filed by Nutrits, dismissed alongside Mayborn’s claims, indicate the defendant mounted an active defence, which may have accelerated settlement discussions.

How the Mayborn v. Nutrits settlement resolved all claims with prejudice
Rule 41(a)(2) dismissal: what it means in practice
A Joint Motion to Dismiss under Federal Rule 41(a)(2) requires court approval, unlike a simple stipulation of dismissal. Here, the Court granted the joint motion, formally closing the case. The with-prejudice designation means neither Mayborn nor Nutrits can return to federal court to relitigate the same infringement or counterclaim theories arising from this dispute — the settlement has permanent legal effect.
Rule 41(a)(2) — court-orderedPrivate settlement terms keep the commercial deal confidential
The Court order confirms the parties ‘settled their respective claims for relief’ but the specific commercial terms — whether a licence, royalty, supply restriction, or lump-sum payment was agreed — are not disclosed in the public record. This is standard in patent settlements. The with-prejudice dismissal does confirm the matter is fully resolved, but the business terms and any ongoing relationship between the parties remain unknown from public filings.
Terms undisclosedEach party bears its own costs — no winner declared by the Court
Judge Gilstrap ordered each party to bear its own costs and fees. In patent litigation, this is often a negotiated outcome within a settlement rather than a judicial finding. It suggests neither party secured a formal ‘prevailing party’ cost award and that the settlement was reached on substantially mutual terms. This stands in contrast to exceptional case findings under 35 U.S.C. § 285, which would compel a fee shift — no such finding was made here.
No fee shiftNutrits filed counterclaims — both sides had active exposure
The dismissal order confirms Nutrits asserted counterclaims against the Mayborn entities, which were also dismissed with prejudice. While the nature of those counterclaims is not detailed in the available record, counterclaims in patent cases commonly include invalidity challenges and/or non-infringement declarations. Their existence suggests Nutrits mounted a substantive defence, and their bilateral dismissal is consistent with a negotiated settlement resolving mutual risk on both sides.

Stipulation of dismissal — official text
The Court’s order confirms a full bilateral resolution: Mayborn’s infringement claims and Nutrits’ counterclaims are both dismissed with prejudice, meaning neither set of claims can be refiled in federal court. The own-costs ruling removes any fee-shift risk for either party. Critically, the order does not constitute a judicial finding on infringement or validity — those questions were never adjudicated. The dismissal is a settlement outcome, not a merits ruling, and leaves the patent US11730680B2 fully in force for enforcement against other parties.
US11730680B2 — Silicone and Plastic Baby Bottle Technology
US11730680B2 (application number US17/562519) is the patent asserted by the Mayborn entities in this action. The patent covers technology relevant to silicone and plastic baby bottle designs, specifically as embodied in Mayborn’s Flexy Silicone Baby Bottle and Plastic Breastmilk Baby Bottle product lines. The application number and resulting grant suggest a relatively recent filing, placing this patent squarely within a modern generation of infant feeding product IP. The patent remains in force following this litigation’s dismissal.
In the infant feeding accessories market — a sector where brand differentiation and product safety claims are central — proprietary bottle design patents carry meaningful commercial weight. Mayborn’s decision to assert US11730680B2 against a market entrant in a high-profile U.S. district court suggests the company views this patent as a core competitive asset. For any company developing silicone or flexible plastic baby bottles for the U.S. market, the claims of this patent represent a material freedom-to-operate concern that warrants formal legal review.
Should your team run an FTO analysis against US11730680B2?
Any company designing, manufacturing, or importing silicone or plastic baby bottles — particularly flexible or breast-milk compatible bottle formats — into the U.S. market should treat US11730680B2 as a priority FTO target. Mayborn has demonstrated a readiness to enforce this patent through litigation in a plaintiff-favourable jurisdiction. Products that share structural or functional features with the Flexy Silicone Baby Bottle or Plastic Breastmilk Baby Bottle lines face measurable infringement risk without a formal FTO clearance.
PatSnap Eureka’s FTO Search Agent can map the claims of US11730680B2 against your product specifications, flag design-around opportunities, and surface prior art relevant to any IPR strategy. Claim monitoring alerts can notify your team if Mayborn files continuation applications that expand coverage. Running this analysis before U.S. product launch — rather than after receiving a cease-and-desist — is the most cost-effective approach to managing this risk.

What this case signals for the infant feeding products IP landscape
Mayborn’s willingness to litigate — and Nutrits’ counterclaim response — reveals active patent enforcement dynamics in the baby bottle technology space.
Mayborn is actively enforcing its baby bottle patent portfolio in U.S. courts
Filing in the Eastern District of Texas before Chief Judge Gilstrap — a high-profile patent docket — signals Mayborn’s intent to use litigation as a commercial tool. Companies operating in the silicone and plastic infant feeding product categories should treat US11730680B2 as a live enforcement risk and assess their product designs against its claims before U.S. market entry.
A 169-day resolution suggests early licensing pressure is an effective strategy
The speed of settlement — before full discovery or any claim construction — is consistent with a defendant concluding that litigation costs outweigh the commercial downside of reaching a deal. For competitors in this space, early engagement with Mayborn’s IP counsel on licensing terms may be more cost-effective than protracted litigation, particularly given Mayborn’s choice of a plaintiff-friendly venue.
Mayborn v Nutrits — key questions answered
The case was dismissed with prejudice on 7 February 2024 following a joint motion by both parties confirming they had settled. All of Mayborn’s infringement claims and Nutrits’ counterclaims were dismissed with prejudice. Each party bore its own costs. No merits ruling was issued by the Court.
Mayborn asserted US11730680B2 (application number US17/562519), a patent covering technology embodied in its Flexy Silicone Baby Bottle and Plastic Breastmilk Baby Bottle product lines. The patent remains in force following the case’s dismissal by settlement.
A dismissal with prejudice is a final adjudication on the merits for procedural purposes. It means Mayborn cannot refile the same infringement claims against Nutrits in federal court, and Nutrits cannot revive its counterclaims. The settlement has permanent legal effect, though it does not constitute a judicial finding on infringement or patent validity.
The Eastern District of Texas, presided over here by Chief Judge Rodney Gilstrap, is consistently one of the most active patent litigation venues in the United States. Patent holders frequently choose it for its established procedural frameworks and significant docket experience. Filing there against an international defendant like Nutrits — an Israeli company — suggests a deliberate strategy to maximise enforcement leverage.
Yes. The dismissal order confirms that Nutrits filed counterclaims against the Mayborn entities, which were also dismissed with prejudice as part of the settlement. The specific nature of those counterclaims is not detailed in the publicly available court record, but counterclaims in patent cases commonly include invalidity challenges or declarations of non-infringement.
